    Ordinary activity slightly limited: angina with walking/climbing stairs rapidly, walking uphill, walking or stair climbing after meals, in cold/wind, under emotional stress, during few hours after awakening, walking >2 blocks on level ground, or climbing >1 flight of stairs at normal pace and normal conditions
    Marked limitation of ordinary physical activity: angina with walking 1-2 blocks on level ground or climbing 1 flight of stairs at normal pace and normal conditions
    Inability to carry on any physical activity without discomfort; anginal syndrome may be present at rest
